What it's good for

A search engine concerned with your privacy, with fewer ads. Works well with the Tor network for extra protection

Nice context/category-based search engine

I've had good results with DuckDuckGo as a replacement for Google, especially for technical/programming searches

A search engine with less garbage and better results. With less clicking forward and back between results, it is for anyone who wants to get information faster

Screens out content farms like eHow

DuckDuckGo is a search engine with built-in disambiguation, Wikipedia integration, and a bunch of site-specific searches. It collects no data on its users by default

If you wish more of the web could be controlled via keyboard, I highly recommend you check out DuckDuckGo: the keyboard search engine

Search engine with less garbage and better results

Duck Duck Go recognizes multiple meanings of words and tries to help you clarify your search, is a selling point for use with younger students who might need help refining their Internet search terms

Simple search engine with clarifying questions

If you search for a term that has more than one meaning, it will give you the chance to choose what you were originally looking for, with its disambiguation results

Duck Duck Go might be the most private place to search the Internet right now. Here's why: No IP addresses. I no longer store IP addresses at all. Not hashes of them. Not remnants of them. Nothing. I don't even log them. No cookies. I don't track you with cookies. If you just come to the site and search, no cookies are set. In fact they're only set if you use the settings page. Https. You can now search on an encrypted connection (using https). And nothing in the logs tells me you are using the https site. No contractors. Actually, it's just me right now, and there are no plans to change this in the foreseeable future. So you don't have to worry about anyone with access stealing the non-IP address logs we do have. No cloud. I run my own servers and network. However, we do have the capability to run on EC2 if needed (in case of network failure). Yet under normal circumstances, your search traffic is running on servers I can actually see :)
